COKE PETROLEUM CALCINED SWK LORESCO 50 LB BAG (70#/cuft) IMPRESSED CURRENT BACKFILL
Corrosion Service offers a full line of Loresco® earth contact backfills and related products which are designed and produced exclusively for the corrosion industry. All Loresco® backfills begin with high-quality carbons that are calcined to exacting standards. These carbons are further processed to enhance various properties depending upon the specific application or field conditions.
Has particle sizes ranging from 0.1 to 12mm. SWK® is heavy and sinks readily in water or light mud. It can be installed by pouring around the anodes, and tamping is not necessary.
The particles of SWK® exhibit a hard, round shape and are composed of almost solid carbon. The bulk density of SWK® is seventy pounds per cubic foot, and the porosity is forty-four percent. SWK® is a product designed specifically for use around anodes in the earth.
Its low resistivity enables intimate anode contact and assures that most electrolytic discharge will occur at the backfill periphery. According to EPA-approved leacherate tests, SWK® meets all purity requirements for materials utilized in burial.
